I've also got this problem with Facebook. I've been 'blocked' from using the official page for a TV programme I like. I can still read the page but I can't post any comments, reply to other people's comments or like/love anything. Also all the comments I'd posted before have been removed. I've tried to investigate why this is but all I can find is other people saying this has happened to them and apparently no explanation is given, there's no right of appeal and you're usually blocked for 60 days. I don't think I said anything controversial but if I did I'd just like to know what it was!
